Answer:
The mass of the second person is 28.91 kg
Explanation:
Given;
mass of the first adult, m₁ = 54.2 kg
distance of the first adult from the point of balance, x = 1.20 m
mass of the second adult, = m₂
distance of the second adult from the point of balance, y = 2.25 m
Taking moment about the point of balance, we will have
m₁x = m₂y
54.2 x 1.2 = 2.25y
2.25y = 65.04
y = 65.04/2.25
y = 28.91 kg
Therefore, the mass of the second person is 28.91 kg
Answer: a meteoroid is debris in space. If part of that debris comes into Earth's atmosphere, it becomes a meteor.

Answer:
The moment of inertia is 0.7500 kg-m².
Explanation:
Given that,
Mass = 2.2 kg
Distance = 0.49 m
If the length is 1.1 m
We need to calculate the moment of inertia
Using formula of moment of inertia
Where, m = mass of rod
l = length of rod
x = distance from its center
Put the value into the formula
Hence, The moment of inertia is 0.7500 kg-m².
Answer: approximately 4 seconds
Explanation:
1.52 is approximately pi/4
2pi rad is 360°
Pi/4 rad is 90°
So the chicken runs one-fourth of the path in one second so it runs the hole path in four minutes
